Which represents the contractual agreement between the service provider and the business?

A. Terms of service

B. End-user license agreement

C. Non-binding user contract

D. Service-level agreement

Refer to the exhibit.

You are expanding the compute layer of a VDC, and need to add more access layer switches to provide connectivity to the hypervisors. However, there are no available ports on the two aggregation layer switches to accommodate the uplink connections from the new access layer switches, and there is no available funding to purchase additional aggregation layer switches. The active uplinks are operating at 95% of capacity.

What can be done to expand the access layer and not impact the performance of the existing environment?

A. Aggregate the aggregation layer switches into a virtual switch. Reduce the number of uplink connections from each access layer switch by 50%.

B. Aggregate the access layer switches into a virtual switch. Reduce the number of uplink connections to each aggregation layer switch by 50%.

C. Aggregate the datacenter core switches. Reduce the number of uplink connections from each access layer switch by 50%.

D. Aggregate the datacenter core switches. Reduce the number of uplink connections from each aggregation layer switch by 50%.

A company has finished the design for their VDC. They realize that they should also include a few design considerations to prepare them for cloud.

What is a key business reason for the company to build a cloud-based service?

A. Speed and agility

B. Cost savings

C. Multi-tenancy

D. Chargeback

What is typically included with an IaaS bundle featuring compute, storage, and networking?

A. Encryption technology

B. Management tools

C. Integrated development environment

D. Storage virtualization

A company has two data centers located within 3 km of each other. They use EMC arrays at one of the data centers; they use non-EMC storage at the other data center. They would like to have a consistent view of one or more LUNs.

Which product should you suggest they deploy?

A. VPLEX

B. Atmos

C. Vblock

D. VNX

The CIO has asked you to review the status of your company's VDC and validate that the implementation has entered the IT-as-a-Service phase.

Which capability must be in place prior to transitioning to this phase?

A. Zero-touch infrastructure

B. Policy-driven automation

C. Self-service

D. Chargeback

Which product performs virtualized data caching across heterogeneous storage arrays?

A. VMAX

B. VNX

C. VPLEX

D. Atmos

Which represent key legal contracts for a service provider?

A. Service level agreement, terms of service, termination agreement

B. Service level agreement, terms of service, enterprise license agreement

C. End user license agreement, termination agreement, service level agreement

D. End user license agreement, termination agreement, performance guarantee

You are using virtual (thin) provisioning to reduce the amount of physical storage that is initially required for an implementation.

On the storage array, you configure a pool that contains 20 TB of physical storage and then define several LUNs that total 100 TB. These LUNs are presented to several hypervisor clusters. Virtual Machines are subsequently created using a thick format for the virtual hard disks.

What is the maximum capacity that can be allocated for VM hard disks in this configuration?

A. 20 TB

B. 100 TB

C. 120 TB

D. 2000 TB

As part of a VDC design, you configured a number of virtual machine OS clusters. Each cluster must have a non-routable network to accommodate system heartbeats. However, some of the clusters house sensitive data that should not be accessible by any other cluster. For fault tolerance purposes, the cluster nodes will never be hosted on the same hypervisor.

How should you instruct the administrator to configure the Private VLANs?

A. Configure the Primary and Community VLANs on both the hypervisor virtual switches and access layer switches.

B. Configure the Primary and Community VLANs on the hypervisor virtual switches.

C. Configure the Primary and Isolated VLANs on both the hypervisor virtual switches and access layer switches.

D. Configure the Primary and Isolated VLANs on the hypervisor virtual switches.
